Serial No. 462,942.

To all whom it may concern:

Be it known that I. F RANK L. ALLEN, a

citizen of the United States, residing at St.

Joseph, county of Berrien, and State of Michigan, have invented certain new and useful Improvements in Steam-Separators, of which thetollowing is a specification.

My invention relates to steam separators, that is to devices for removing the water of I condensation from the steam before conducting the latter to places for further use.

Although my invention maybe used in conjunction with almost any steam operating or consuming device, it is particularly adapted for use with paper web drying ma chines, and I have so illustrated it in the ac companying drawings and described it in the following specification. The object of my invention is to provide means for removing the Water of condensa tion from a; rotating member through which steam is passing in order to maintain said member substantially free of water and to separate the 'ater andthe steam so that the latter may be again used without being contaminated or mixed with the water of condensation.

Other objects will appear hereinafter.

My invention will be more readily under stood by reference to the accompanying drawings forming a part thereof and in which Figure l is a vertical longitudinal section t-'-.rough one end ofa cylinder of a paper drying machine, equipped with a. steam separator embodying my invention in its preferred form. Fig. 2 is an enlarged detail section of the journal and the adjacent parts. Fig. 3 is a front elevation of one of the separators partially in section.

Referring to the drawings. 1 indicates the cylinder of a paper drying machine or other rotary member through which steam is adapted to pass, and 2 a hollow journal for the same which is supported in formed ina frame 4. The cylinder 1 is provided with a head 5 upon which the journal 2 is formed.

Fixed to the end of the journal portion 2 is a tubular extension 7 which is arranged in axial alinemcnt with the portion 2 and forms part of the journal. The inner end of the extension 7 is provided with a. peripheral flange 6 through which the bolts extend for attaching the extension to the portion bearin 3 j The bore of the extension" is somewhat snmller than the bore of the journal 2. j The inner end of the extension 7 is formed 1 with an annular seat 8. whose face is contcavcd and ground to fit tightly against a packing ring 9. said ring having an interior I diameter considerably less than that of the. bore of the journal 2. Extending from the I packing ring and preferably formed integrally therewith is a tubular sleeve 10 which tits within the-extension For the same. The sleeve 10 extends beyond the outer end of the extension 7 and is threaded for connection with the casing of the steam separator proper. The packing ring Tt'orming a lining t jlll cross-section is the segment of one ot the, Hat tacos of which bears against the inner end .of the journal 2, 'while its curved or-convcx taco bears against the seat 8.

The 'ater collecto' and steam separator comprises a rectangular casing 11 which is attached to and supportml by a hanger l2 loosely mounted on the journal extension 7. The extension is reduced in diameter as at 123 to receive the. hanger l2. and the hanger is widened out at its bottom to form a plate 14 to which an upwardly extending flange if on the inner edge of the separator is attached by bolt 16. At the upper end of the separator is an inletopening 17 formed with a nipple for the attachment of ajconducting pipe conveying steam from a boiler or other source of supply, while directly opposite is an outlet opening 18 having a nipple to which a conducting pipe '19 is attached leading to another source of steam consumption.

The upper end of the casing 11 is pro vidcd with a partition which divides the separator into two chambers 21 and 22. This partition extends .dmmwardly from the top of the casing at: one side of the opening 23 leading from the sleeve '10 to a point below the level of the inlet pipe '17 and then extends to the side of the separator below the entrance of the pipe. The sleeve 10 is threaded into the aperture 23, hence the inlet chan'iber 21 is in direct communication' with the cylinder 1 sleeve and the bore of the journal 2.

Tiocated within the tubular journal 2 and its extension 7 and suitably spaced therefrom the inner end of which is downwardly turned 1 and extends to a point adjacent to the lowa circle.

through said is a stcanr and water conducting pipe 24} .22. The pipe 24 is for est point of the cylinder. At its outer end the pipe 24 projects through the extension 7 and terminates in an elbow 25 which extends through the partition 20 into the chamber the purpose of conducting steam and condensed water from the. cylinder to the separator, while the annular space surrounding the same is for the purpose of conducting the steam from the inger chamber 21 to the interior of the cylm er.

In order that a steam tight joint shall be I made between the rotating journal-extension ring into 7 and the said lining 10,50 that steam may not escape around the lining or at the junction of the journal with the separator, I

provide the expansible thrust collars 26-27,

workin in connection with the packing ring 9 and lining sleeve 10. The rear face of the upper end ot' the separator is formed with a sl'ioulder 28 and located between this shoulder and the end of the extension 7 are the expansible thrust collars above referred inder' rotates these two surfaces will move upon each other and "soon wear to a tight joint, thereby preventing steam from ,passing out around the outer face of the packing ring. At its forward end of the sleeve 10 is connected to the separator by a steam tight joint. It will be seen from the foregoing description, that l have provided a rotary packing which is kept constantly steam tight and which operates automatically to provide a ground joint for itself.;

At the lower end of the-compartment 22 of the separator, I provide a water drain pipe ill. the opening to the drain being controlled by a valve'32 operated by a float 33 pivoted on brackets projecting from the side of the casing. The float is so adjusted that it will close the valve before the water sinks to the level of the pipe 31. The lower end of the casing may movable plate 34 whereby the casing may be cleanet out whe'n'desired, or the bal valve adjusted.'

. in'g from the upper portion of the casing be provided with a re- The operation of the device is as follows: Steam is admitted through the pipe 17 into the compartment 21 of the separator, from which-it passes by the annular inlet 35 to the interior of the cylinder 1. The water; of condensation will accumulate at the lowest point of the cylinder around the mouth of the pipe 24. If the water is deep enough to cover the mouth of the'pipe the steam entering the cylinder will positively force the water out through .the pipe and into: the compartment 22 of the separator. The waterwill fall to the bottom of the separator and' the steam will pass out the opening 18 andpipe 19 to a further source of steam eon sulnption.

Having described my invention what I claim as new and desire to secure by Letters Patent. is:

1. In a device of the class described, a rotary cylinder having a tubular journal, a. separator casing suspended loosely from said journal, a drain pipe in the lower portionot said casing, a steam conducting pipe leada compartment formed in the upper portion of the casing having connection through said tubular journal with the interiorof the cylinder, means for admitting steam to said.

compartment, and a steam and water'outlet 90 pipe leading from the lower portion of the interior of said cylinder through said jour nal and said compartment into the lower portion of said casing, substantially asdescribed.

2! In a device of the class described, a

suspended loosely from said journal, a partitionin said casing dividing the same into two compartments, a drain pipe in the low;v est portion of one of said compartmentsfa steam conducting pipe leading from the upper portion of the same, the second Zoom-, partment beingv in communication with said cylinder, means for admitting steam to said second compartment,ai1d a steam and water 105 outlet-pipe leading from the lowest portion of theinterior of said cylinder out through said journal said second compartment said partition into the first said compartf ment, substantially as described.
